UNITED STATES PATENT OFFHCEQ SAMUEL H. BARTLETT, OF NEW YORK, N. Y.

PORTABLE GALVANIC BATTERY.

SPECIFICATION forming part of Letters Patent No. 228,972, dated June 22,1880.

Application filed J anua'ry 23, 1880.

bination with a closed reservoir attached to one end of the aforesaidcell, and communicating therewith by an opening midway, or thereabout,of the depth of the cell, said opening being provided with a suitableplug or valve for the closing of the opening when occasion requires.

In order to use the apparatus as thus constructed the reservoir istilled with any of the usual exciting-liquids, and the opening isclosed, as hereinbefore explained, whereupon the apparatus may becarried either upon the v person or in a valise, trunk, or the likewithout danger of spilling the liquid.

When the battery is to be applied for actual battery purposes the plugis removed, the apparatus is turned into a horizontal position, andone-half, or thereabout, of the excitingliquid passes into the cell, andby submergin g the zincand carbons to the requisite degree puts thebattery in operation.

' Figure 1 is a plan View, and Fig. 2 a vertical central longitudinalsectional view, of an apparatus embracing my said invention.

A is the cell, fitted in the usual or any suitawhich is entirely closedexcept for the opening a, which is situated midway, or thereabout, ofthe depth of the cell, and, of course, of the reservoir. A suitableplug, 1), or in lieu thereof a valve of any appropriate construction, is

provided for this opening.

When the exciting-liquid is placed in the reservoir, and the opening isclosed with the plug or its equivalent, it is manifest that theexciting-liquid will, so to speak, be bottled up, and cannot be spilledduring any ordinary movement or transportation of the apparatus. 011 theother hand, when the plug is removed and the apparatus placed in ahorizontal po; sition the liquid will flow out into the cell; and byfilling the lower part thereof, and to a corresponding extent submergingthe zinc and the carbons, will put the battery in operation.

It is, of course, to be understood that the cell, together with thereservoir and the plug, is to be made of vulcanized india-rubber or"other material practically incorrosive from contact with theexciting-liquid.

What I claim as my invention is A galvanic-battery cell having attachedthereto a reservoir, D,- communicating with said cell by an openingmidway, or thereabout, of the depth of the cell, and. provided with asuitable plug or valve for closing the reser* voir when required, allsubstantially as and for the purpose herein set forth.
